Free remotely hosted cgi scripts in webThe security of the web resources and corporative resources is one of the most disturbing issues for the system administrators all over the world. The number of different incidents is growing up by exponential dependence. The growth of the malefactors' activity depends on the expanding of the Internet and the appearance of new hosts.
Hackers' attacks can be classified in the following way:
-violations that are based on the defects of the protocols;
-used defects of the operation system;
-attacks that use internal defects of the used applications. For instance, the free remotely hosted CGI scripts are affected by the risk of attacks.
-Exploiting the human weaknesses. In this case, the users' computers are addicted to the Trojan infection.
The most popular types of security violations are tries for unsanctioned access, scans, DoS attacks and tries for the incorrect applications usage. The hackers use the vulnerability of the browsers and the weak sides of the free remotely hosted CGI scripts very often. They develop worms and viruses for this purpose.
There are more than one thousand new worms and viruses detected in 2005. There are polymorphous and metamorphous types of the worms. The developers use some special tools to mask them. Some types of this malicious software detect some possible vulnerabilities of the infected PC and transfer this data to the author by the IRC channels. There are some worms that can eliminate other adware that is present in the PC.
The internal structure and functionality of the worms becomes more and more complex. They can define the specific objects for the attack. Worms and viruses use the information resources, such as search systems and message boards. In this way they can decrease the probability of detection and increase the number of violations.
Earlier, most part of the attacks was performed for hooliganism or hazard. Currently, almost one hundred percent of the attacks have some criminal purposes with a commercial interest. The hackers develop and sell the lists of the violated hosts for sending spam, fishing and DoS attacks. At present, these attacks are performed for the half legal business, such as hazardous games in the Internet, porn resources, etc. Lately, there is a tendency for the network attacks with a political motivation. This tendency means a growing professional level of the invasions and security violations. The free remotely hosted CGI scripts can be listed among the most probable targets for this activity.
There is a huge amount of menaces that can affect any user, who works in the Internet. Some of them are a sequence of the complex information technologies and the usage of free remotely hosted CGI scripts, since they are addicted to the external impacts. Some security problems are connected with objective hardware problems, such a slow quality of the power supply, electromagnetic noises, however, most part of them are consequences of the users' inaccuracy and negligence.
